Definitions

  • the invention relates to a device for coupling the cooling medium guide of a rotary part according to the preamble of the main claim.
  • a generic device for coupling the cooling medium guide of a support and transport roller is known.
  • This device is supported by journals in bearing blocks through roller bearings and a cooling medium flows through it through an axial bore through the journals.
  • Each bearing block is closed by a cover and the cover has a cooling channel which is connected at one end to a coolant supply and discharge and ends at the other end in the region of the pin bore.
  • a compensator is provided between the channel mouth of the cover and the bore of the roller which interacts with a seal which coaxially touches a sealing surface arranged to the roller axis.
  • the seal is preferably designed as a lip seal.
  • a disadvantage of this construction is that the sealing lip of the sealing ring is subject to wear due to the movement that takes place on it and is therefore limited in its service life. Furthermore, the temperature range that can be covered is limited because lip seals are usually made of elastomers. In addition, the compensator cannot be preloaded in a targeted manner, so that an adaptation to different internal pressures of the cooling medium is not possible.
  • the object of the invention is to provide a durable device of the generic type with which the disadvantages described can be avoided.
  • REPLACEMENT BLA ⁇ (RULE 26) can be enlarged.
  • the previously usual temperature limitation due to the use of an elastomer for the lip seal is no longer applicable here.
  • the service life of the device is significantly extended because the wear rate of a mechanical seal is significantly lower than that of a lip seal.
  • the hard and wear-resistant material used for the mechanical seal such as B. silicon carbide is able to grind the dirt particles that may have been carried along with the cooling medium.
  • the arrangement of the compensator together with the mechanical seal in a receiving sleeve makes it possible to carry out the pretensioning by varying the distance between the cover-like flange and the frame element of the bearing of the rotating part. This variation of the preload can advantageously be used to adapt the effect of the internal pressure of the cooling medium to the effect of the compensator.
  • the proposed device can be used for both fast and slow-running rollers, rollers or the like, since the appropriate adjustment is possible via the choice of material and the size of the sealing surface of the mechanical seal.
  • Possible leaks of the cooling medium in the area of the mechanical seal can be easily removed through an opening made in the cover-like flange, for example. This prevents the cooling medium from undesirably mixing with the lubricant for storage.
  • the controlled escape of the cooling medium at a defined location after damage to the seal is desirable so as not to wet the product manufactured in the system.
  • the newly developed design can also be used for rotary parts in which one side is not available for a cooling connection, for example by connecting a drive unit.
  • the duo principle is used, in which both the supply and the discharge of the selected cooling medium is carried out from one side.
  • a tube is arranged in the bore of the rotary part, the outer diameter of which is smaller than the inner diameter of the bore. This tube extends through the compensator and the mechanical seal and is connected to a feed or discharge connection arranged in the receiving sleeve.

  • FIG. 6 shows a fourth embodiment in a longitudinal section comparable to FIG. 2.
  • Figure 1 shows a partial longitudinal section and Figure 2 is a view in the direction X of Figure 1 shows a first embodiment of the device according to the invention.
  • the end region of a pin 1 of a rotary part, not shown, is covered by a frame part 2 of the bearing, not shown, by means of a seal 3.
  • the pin 1 has an axially extending bore 4 through which the cooling medium is guided.
  • a recess 5 is arranged in the center, into which, for example, a collar sleeve 7 having a threaded section 6 is screwed.
  • the collar sleeve 7 has a collar-shaped collar 8.
  • This collar-like collar 8 is preferably provided with two flats (not shown here), so that a corresponding open-end wrench can be used to screw the collar sleeve 7 in place, or a flange connection is also possible.
  • the end 10 of the compensator 11 facing the frame part 2 is fastened in a rotationally fixed manner, for example by means of a weld seam.
  • the opposite end 12 of the compensator 11 is rotatably connected to a slide ring 13 of a mechanical seal, for example also by means of a weld.
  • the fixed slide ring 14 of the mechanical seal is arranged on a floor-like shoulder 15 of a receiving sleeve 16 in a rotationally fixed manner, for example by means of an injection.
  • the slide rings 13, 14 of the mechanical seal are preferably made of silicon carbide and are therefore hard and wear-resistant.
  • the receiving sleeve 16 has a bore 18 provided with a threaded section 17. A corresponding coolant line can be screwed into this threaded section 17

  • the receiving sleeve 16 has a radially outwardly extending collar 19.
  • a lid 20 comes to rest on this collar 19.
  • the cover 20 has four bores 21, 21 ', 21 ", 21 * " through which connecting screws 22, 22', 22 " > 22 '" can be inserted.
  • the cover 20 is fastened to the frame part 2 by means of these screws 22 to 22 "'.
  • the preload can be reduced.
  • the cooling medium is to flow through the device from left to right, here indicated by an arrow 24.
  • the cooling medium also flows through the compensator 11, which is acted upon by the internal pressure of the cooling medium.
  • the given bias of the compensator 11 and the internal pressure of the cooling medium interact in such a way that the force necessary for the sealing effect is achieved.
  • FIG. 3 and 4 show a second embodiment of the device according to the invention in the same partial longitudinal section and view as FIG. 1 and FIG. 2, the same reference numerals being used for the same parts.
  • an eyeglass-like disk 25 is used here, which interacts with the receiving sleeve 16.
  • the distance influencing the preload of the compensator 11 is set in this example via the spacer sleeves 26, 26 'comprising the connecting screws 22, 22'. Since in this case the space between the washer and the pin 1 is open, a seal 27, secured by a snap ring 28, is arranged between the collar sleeve 8 and the receiving sleeve 16. If a drainage opening is required, it would have to be arranged in the cylindrical part of the receiving sleeve 16 in this case.
  • Figure 5 shows a further embodiment in the same partial longitudinal section as Figure 1.
  • the same parts are provided with the same reference numerals.
  • This embodiment is necessary if the other side of the rotary part, which is not shown in more detail here, is not available for a coolant connection because, for example, the drive for rotating the rotary part is on this side
  • REPLACEMENT BLA ⁇ (RULE 26) is attached.
  • a tube 29 is arranged in the bore 4 of the pin 1, which has a smaller outer diameter than the inner diameter of the bore 4 of the pin 1.
  • This tube 29 extends through the collar sleeve 7, the compensator 11 and the mechanical seal and is attached in a differently designed receiving sleeve 30.
  • This receiving sleeve 30 differs from that shown in FIG. 1 in that it has a feed connection 31 and a discharge connection 32. The function of the two connections 31, 32 can also be interchanged.
  • the open end of the receiving sleeve 30 is closed with a cover 33. The effect of the mechanical seal in combination with the compensator 11 is the same as described above.
  • Figure 6 shows a second variant, being the counterpart to Figure 3 with respect to Figure 1.
  • the cover 20 is replaced by an eyeglass-like disk 25 and spacer sleeves 26, 26 'b cooperating therewith.
